Description

-ν-

Each of the two transverse rods 4 is articulated at its two ends, via the connection points with the brakes, to an axle 5, which is carried by the piston rod 6 a of a pneumatic or hydraulic actuator 6, the cylinder 6 b of which is connected to a joint 7 one of the arms of a Winkclhebcls 8 is articulated. This angle lever can be pivoted about an axis 9 which is seated on a bracket K) which is firmly connected to the longitudinal member 2.

The other arm of the angle lever 8 is connected via a swivel joint 11 to a rocker 12, which is also pivotably mounted on the axis 5 (FIG. 3). A number of übereinandergclcgten Einstcll-Zwischenlagcn 13 interposed b between the Gclenkkopf the piston rod 6 'and the cylinder 6, the adjustment of the height position allowing the magnetic rail brake with a completely retracted position of the actuating devices 6, which occupy this position under the action of the pressure medium, which is introduced into the lower working space 6 c of each of these actuators.

Under the effect of centrifugal force, the entire, from the magnetic rail brakes and the Traverses existing pendulum assembly to the outside of the track curvature relative to the bogie pivot, the four articulation systems, each with an actuating device 6, an angle lever 8 and a rocker 12 include, deform accordingly.

The distance E between the joint axes 5 and 9, which represents the length of a fictitious pendulum rocker connecting these two axes, is selected to be significantly greater than the length of a transverse pendulum that may be present between the car body and the bogie frame.

Before actuating the magnetic rail brakes, the magnetic rail brakes 1 must be brought into their middle position vertically above the rails. Zv. For this purpose, the two rail brake bodies are connected to one another in the central transverse plane of the diehgcslcll by a connecting rod 14 (FIG. 4) which is pivotable about an axis 15 on each of the rail brake bodies. which sits in a fork bracket 16 firmly connected to the brake body: this axis also forms the joint of a lever 17, which is connected in its center via a joint 18 to the piston rod 19 a of two actuating devices 19, which are connected to a joint designated 20 is hinged to a carrier 21 fixedly connected to the rod 14. The upper part of the lever 17 is in the form of a cylinder body 22 which, under the action of the pressure medium fed into the working spaces 19 b of the corresponding actuating device 19, is intended to apply to a stop 23 fixed on the bogie frame. This stop sits on a beam 24 which is fixed between two box bodies 25 which are carried by the longitudinal beam 2 and are intended for fastening the transverse stiffeners (not shown) which connect the longitudinal beams 2 of the bogie to one another.

The transfer of the braking force of the magnetic rail brakes is carried out on the bogie frame by means of a triangular link system (Fig. 1 and 2). that sits on the bogie frame and one at each end of the magnetic rail brake 1 Has pendulum lever 26 which angclcnkt to the longitudinal beam 2 at a joint designated by 27 and is connected via a joint 28 to a push rod 29, which in turn is connected to one designated by 30 Joint is articulated on the axle bearing housing 3. The Pcndclhebel 26 is with a support sole 26a, against which a Glcit-Druckplattc 31, which is firmly connected to the transverse rod 4, rests can.

In FIG. 4 is the pendulum system approximately

in its outermost pivoted position, the pendulum movement being limited by the support of the cylinder body 22 of the lever 17 on the fixed stop 23. In order to bring the magnetic rail brakes 1 back exactly vertically over the rails, pressure medium is fed into the working space 19 b of the actuating devices 19. The cylinder of the actuating device is then supported on the piston rod 19 a and is moved after the application of the cylinder body 22 to the stop surface 23 a together with the connecting rod 14 and the magnetic rail brakes 1 in the direction of the longitudinal axis of the bogie. The return movement is now limited by a stop 17a, which is provided on each of the two levers 17 and reaches a limit stop 1a, which is provided on each of the magnetic rail brakes (FIG. 5). Of course, the return movement is carried out by one or the other of the two actuating devices 19, depending on the direction in which the brake arrangement was pivoted out in a pendulum manner.

After the return of the magnetic

brake in their symmetry relative to the Länesachsc of the bogie, which is limited by the stops 23, causes an introduction of pressure medium into the upper working spaces 6 d of the actuating devices 6, the lowering of the entire, consisting of the magnetic Schicncnbremsen I. the cross rods 4 and the connecting rod 14 Assembly until the magnetic rail brakes 1 are placed on the rails. The actuating devices 6, the angle levers 8 and the rockers 12 assume corresponding positions caused by the lowering movement of the magnetic rail brakes 1.

When stopping the magnetic braking, does it cause? Introducing pressure medium into the lower working spaces 6 c of the actuating devices 6, the lifting of the entire pendulum puffed up again

position, lowering and raising again de Ensuring magnetic rail brakes is very schematic as an example in FIG. 6 illustrates.

The circuit diagram of FIG. 6 relates to the special case where the actuating device hydraulic piston drives are: it may however, it should be clear that the operating devices intended for lowering and raising again are in order or the return devices for returning the magnetic drive braces to their central position can also be pneumatic piston drives.

The feeding of pressure medium into the cm or other of the two work spaces 6 c or (

Each of the four actuators 6 is controlled by an Elcktroumschallventil (Elcktroumschallventil) F. In In the same way, the working medium is let into the working spaces 19 /; and 19c of the two BeO igungsvorrichtungen 19 by a corresponding Electric valve C.

The electrical control circuit for the solenoid valves F and C contains a relay R with four normally open contacts; ·, to C ₄ and also includes two manually operated switches A and B designed as push buttons.

A double pressure switch M, which is fed with pressure medium from the working spaces 19 c of the two actuating devices 19 towards the end of the piston stroke, actuates a switch or contact D for feeding the actuating winding of the solenoid valve F.

Braking is triggered by pressing the push button switch A; the resulting excitation of the winding of the relay R causes the four relay contacts i \ to / y to close, the excitation of the relay is maintained by the holding contact; ·. The closing of the contact r ₃ , which is connected to a timing element T _n , which only becomes effective when this contact is opened (and is only illustrated schematically in the circuit diagram by a rectangle in the current between the contact and the coil), immediately excites the actuating winding of the solenoid valve C, which now controls the admission of pressure medium into the working spaces 19 b of the actuating devices 19. One or the other of these two actuating devices now causes the return movement of the entire pendulum system and after reaching the end position of the two actuating devices 19, i.e. after setting the magnetic brakes in their working position, the double pressure sounder / V / closes the contact D, which now together with the Contact;. ·, and only becomes effective at the closing of this contact Zeitverzögerungsgliedcs Tf causes the excitation of the actuator coil of the solenoid valve F,

The Magnetschicncnbremscn 1, the excitation of which was caused by the coil P when the relay contact r ₄ was closed, are applied to the rails under the action of the actuating devices 6 and pressed by their own magnetic force.

To raise the magnetic rail brakes 1, the push-button breaker switch B is operated to make the relay R drop; opening the contact r ₄ interrupts excitation of the magnetic rail brake and opening the contact; "switches off the power supply of the solenoid valve F, which is now the Untcrdrucksctzcn the lower working chambers 6 c of the actuators 6 for the purpose of lifting of the magnetic rail brakes causes. Opening the contact r. _t , in which the interruption of the current is _{delayed by the timer T n} , the electrovalve C switches over in such a way that this valve now the working tears 19 c of the actuation device
